java.lang.Object
  org.proteinshader.math.HermiteDemo

public class HermiteDemo
extends Object

Performs some simple tests on the Hermite class.

Field Summary

static int

SEGMENTS The number of segments to divide the curve into is 10, so the total number of points printed will be 11, including the points for t = 0.0 and t = 1.0.

Constructor Summary

HermiteDemo()

Method Summary

static void	main(String[] args) Creates a start and end point (each with a tangent vector) to plug into a Hermite object.
static void	printCurve(Hermite hermite) Uses the Hermite object to obtain and print interpolated points from parameter t = 0.0 to t = 1.0.
static void	printStartAndEndPoints(Point3d p1, Point3d p2, Vec3d tan1, Vec3d tan2) Prints the start and end points along with their tangents.

HermiteDemo

public HermiteDemo()

Method Detail

main

public static void main(String[] args)

Creates a start and end point (each with a tangent vector) to plug into a Hermite object. A helper method is then used to increment parameter t from 0.0 to 1.0 while printing the points (and tangents) in between the start and end points. When graphed, these point should form a curve.

printStartAndEndPoints

public static void printStartAndEndPoints(Point3d p1,
                                          Point3d p2,
                                          Vec3d tan1,
                                          Vec3d tan2)

Prints the start and end points along with their tangents.

Parameters:

p1 - the start point

p2 - the end point

tan1 - the tangent of the start point.

tan2 - the tangent of the end point.

printCurve

public static void printCurve(Hermite hermite)

Uses the Hermite object to obtain and print interpolated points from parameter t = 0.0 to t = 1.0.

The total number of points is SEGMENTS + 1, and each point is printed along with its tangent.

Parameters:

hermite - a Hermite object with a start and end point.
